Admitting the release over the weekend was "pretty rocky," The
Steam News Page (thanks David Cronk) says that today Valve "will
release new installers which include the cache files for all of the games
available via Steam (Day of Defeat, Team Fortress Classic, the dedicated server,
etc). If you haven't already done so, please use the installer that includes
Counter-Strike and Half-Life." The update goes on to point out: "We
know that the conversion process has been anything but smooth for many of our
users. We're going to get this fixed. We've done our best to support the
Half-Life community over the past 5 years, and we're still committed to doing
whatever it takes to make the community happy."
